ARTIFICIAL FUEL AND METHOD OF MAKING SAME.

SPECIFICATION forming part of Letters Patent No. 774,682, dated November8, 1904.

Application filed January 23, 1904.

T0 ctZZ whom, it ntay concur-n:

Be it known that I, MICHAEL F. MAGINNIS, a citizen of the United States,residing at Philadelphia, in the State of Pennsylvania, have invented anew and useful Artificial Fuel and Method of Making Same, of which thefollowing is a specification.

This invention relates generally to an artificial fuel and method ofmaking the same, and more particularly to one adapted for the use insteam-boiler furnaces where soft coal is now employed.

The object of the invention is to provide a composition which will becheap and efiic ient and one which willnot be affected by climaticchanges, and one which will not dry out and blow away when permitted toremain for any considerable length of time.

Another object is to provide an artificial fuel which will be ready foruse as soon as the ingredients are thoroughly commingled,

thereby avoiding the necessity of briqueting,

and baking the mass.

With these various objects in view my invention consists in the variousingredients hereinafter referred to and combined in the proportions andin the manner hereinafter set forth.

In carrying out my invention I employ two thousand pounds of bituminouscoal finely powdered, to which is added forty pounds of anthracite-coalashes finely sieved. These ingredients are thoroughly mixed in a coldand dry state. I then prepare a solution consisting of one hundred andtwenty pounds of salt and seventy pounds of water at atemperature of 130Fahrenheit, and the coal and Serial No. 190,381. (No specimens.)

ashes are then added to this solution and thoroughly mixed for a periodof two minutes, and I then add twenty pounds of meal, the residue oflinseed-oil for the purpose of waterproofing the composition. It alsokeeps the mixture in a moist condition, so that in easea quantity ofthis fuel should remain about the furnace-room or other place it willnot dry out and be blown away, but will remain in a semiplasticcondition, so that none ofthe fuel is Wasted by permitting it to liearound.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. An artificialfuel composed of two thousand pounds bituminous coalfinely powdered, forty pounds of anthracite-coal ashes finely sieved,one hundred and twenty pounds of salt and seventy pounds of watertogether with twenty pounds of meal, the residue of linseedoil.

2. The herein-described method of preparing artificial fuel, whichconsists in mixing together finely-powdered bituminous coal, and

anthracite-coal ashes, in the proportions set forth, preparing asolution of salt and water in the proportions and at the temperaturenamed, then mixing the coal and ashes with the said solution for apredetermined time and then adding meal, the residue of linseed-oil inthe quantity specified, and thoroughly mixing the entire mass.

MICHAEL MAGINNIS.
